Mirage 2000 with ducts.

I saw the mirage that Diymik posted and the fact he said it is not flying for him yet. I reworked the 2 middle parts so that the ducting was in place. I might still need to smooth out the ducting to prevent vortex pockets.
When printing this set of parts you need a top and bottom layer unlike the originals. You also need 5 to 10% infill unless your printer is very good at bridging.
